PHILIP MUELLER, OF DECATUB., ILLINOS.

'Lenssen ToaZZfL'Uiom-'tmay concern: Y i i Be it `known that 1, PHILIPMniinnnn, a

citizen' of the United States,` residing at Decatur, in the county ofMacon andState of Illinois, have invented new and useful Improvements inBubbleiHeads for Sanitary Drinking-Fountains, of which the following isa specification.

.The present invention relates to sanitary drinking fountains, andparticularly to that type in which a drinking bubble is projected above;the surface 'of the delivery. nozzle,

which drinking bubble may be continuous,

or may beintermittent and controlled by a suitable valve which willbeturned on by the user. A

My invention relatesV particularly tothe nozzles orv bubbler headregardless of the` othereaccessories of the fountain.

Oneof'tlie objects of my invention is to` provide a nozzle whichmay beconstructed principally ofxmetal, for convenience and cheapness in`manufacture and assembling,

but in -which porcelain or other suitable,

vide a bubbler head which is entirelysani-` tary, and-n which failure ofthe bubble, by

reason of clogging of the Ydischarge orifices in the head, cannot takeplace, andin .which furthermore, the matter of clearingv any o thedischarge orifices `which may become clogged byfforeign matter iseasily' accompl'ishedf; 1W. In order that the invention may be clear tothose skilledin the art, I have shown herein one embodiment ofthe-invention, but itwill vbe understood that the construction may bevaried within the range ofimechanr cal skill from 4the specificdisclosure Vhere made ,without departing/from the spirit of myinvention.A

Application filed January 3, 1917. Serial No. 140,388.

'Referring' to the drawingsby numbers,

like numbers indicating like` parts in the several views, indicates anysuitable supply pipe, andll any suitable stand pil e,

the stand pipe in the present iijistancebeing shown as provided with asuitable valve Vwhichmay be of the self-closing type, and

which controls flow to the bubbler head.

Mounted on said stand pipe is the bubblei' head 12 composed of the metalbody portion 13,-wliich is enlarged or flared from the stand pipeconnection upwardly, so as to give a chamberof considerable capacity, inwhich chamber, if desired, may be mounted any regulating 4means to cut`down the volume to be delivered, if such regulating means is necessary.The regulating means is not shown, as it may takevarious forms, and-I donotconfine myself to any particular type, if suchregulation is foundnecessary. ,Y

Theenlarged chamber of the bodynpoitionf13 is screw-threaded, preferablyon its` interior toreceive a 4metal ring 14;, said metaly ring engagingat its upper end a; seat 15 formed ina porcelain cover plate 16, thesaid ring and plate being secured together, preferably by cement, asindicated at 17, so as to form substantially an integral structure.v"ItQwill `be `observed that the metal ring 15 is of smaller diameterthan the porcelain cover plate 16, so that kwhentlie ring 14 is screwedinto the body portion the porcelain cover plate will A rest upon the topof the body portion and make ai close and iinished joint therewith.

-The cover plate 16 of porcelain is,.in` the present embodiment, shownas substantially fiat, having the depending rim in which the seat 15 isformed, this depending rim eX tendiiigdownwardly a. short distance so ast0 give an attractive appearance, and a coinpletely sanitary vitreoustop.v By forming the cover plate ltin the manner shown, and assemblingit` with the metal ring 14 asdescribed, construction is provided whichmay be very readily se curedto the vbody .portion 13,and in event ofbreakage of the porcelain cover plate the sam'ezmay be replaced, withoutdisturbing the body portion proper, either by substituting a .new cover,plate and metal ring, or by cementingfa new cover plate-to said' ring.By providing the porcelain cover plate with the short depending rim, avitreous surface is p lovdekd'ofisufcient area` to give an entirelysanitary nozzle Without the necessity of forming the entire nozzle ofporcelain, and, furthermore, one in which the surface will notcorrode/or` discolor in use.

The cover platel is provided VWith discharge or-jetE-forming orifices18, circularly disposed about the axis of the cover plate, and theseorifices 18 are so placed as to -deliver converging jets to the centerof the bubblerhead, so' that the meeting streams will forma bubble orgeyser, which Will ber projected a considerable distance above the head.In the vparticular embodiment shown the orifices 18 are inclined gtobringV about this meeting of thejets, but it Will be understood that Ido not limit myself to the particular j inclinationor direction of thejets here disclosed.

It will be observed that the jet orifices 18 arek arranged in aplurality of radially disposed series, so that thereivill? be projecteda plurality of streams toward the center as distinguished z from thattype of lfountain now in use, in which a single circularly disposedroWof jets or nozzles Vare provided which meet at the center and form abubble. The-advantage of a plurality of ets directed substantially to acommon central point over that` type of-'fountain in Which a singleycircular row of jets deliver to a central point, is-that if,"for anyreason, one of the radially disposed jets is stoppedl by reason ofclogging of thedischarge orifice, the drinking fountain Will not bedestroyed,ffor the other jet orjets will preserve that bubble andprevent sprayingV of the Water to l one side,`

which always occurs in the type offountain toWliichiIhave referred, iffor any reason one of the single circlelof-jets is stopped.

11 The'advantage of this plurality of radially disposed "jets al1delivering to the center is that not only will the `drinking bubble`bepreserved though one or more of the discharge orifices be clogged,but danger of'discha'rging Water from' the fountainV and onto lthe flooris eliminated. A j Y lltwill be-understood that such changes as aremerely mechanical expedients, and substitution of equivalent elementsfor those hereindisclosed, are to -be regarded as Within the range of myinvention.
